If you have several 240v loads and no requirement for the 120v star connections then, it may be prudent to look for a 230/240v transformer.
Although if you have quite a few devices, it will require a large unit.
I would look at hooking up the 480 volt devices direct the incoming power if there are a few such as the 10hp motor.

Okay good to know. This is one of the older machines in place and newer machines have been hooked up to 480V when possible. Just wanting to increase the longevity of those machines that aren't compatible with 480V. Thanks for all the advice!

 

The power supplied from the panel is 208v. The voltage drops to about 202-204v when the motor is running. The system has been in place for about two years with no issues but has always run warm. I think the problem was exacerbated by high ambient temperature this summer as I had other pieces of equipment overheat as well that have run fine for a couple years. I think the problem lies with the supply voltage of 208v being too low for the service factor of the motor which states 230v on the nameplate. Installation error is certainly a possibility as well but I’d like to hear your story!

It is a rather sad tale. One part of a machine I designed included two 4 inch wide chain link conveyors. I designed the drive to use 1/4 HP 480 volt 3 phase gearmotors, with the connection to drive them with a 2 inch sprocket on the gearbox and a 3 inch sprocket on the conveyor shaft., thus a 3:2 reduction. Just before shipping the forman decided that was not fast enough, and as there was no time to get different motors, they altered the sprockets so one drive was 3inch to 3 inch and the other was 2 inch to 2 inch. This provided no reduction and moved a fair amount faster. Unfortunately it resulted in the motors being just a bit overloaded., and running a bit too hot. And the environment was a sintered metal plant that was hot in the winter with half of the windows open. ( the plant did not normally run the heating system. so the motors eventually failed, and I was asked why I did such a goofy design. I explained that the change was made by others and that I originally had the 2:3 reduction. The replacement gearmotors were 1/3 HP. My perfect record was damaged a bit.
